Hi , comp cams solid and hydraulic rollers are made of Austempered cores and can use a std Iron gear, a specially ordered billet steel roller needs the bronze , or the new ultra-poly gear, Im pretty sure you can use that on anything.When I was in the USA last year I went to Mc Master Car , think thats a nation wide engineering supply place ,They sell a heavy duty roll pin 1/8 th The same design as MSD use , that sort or of roll pin will out last the hardened tension pin .
